I think that the monarchy would care as the UK obviously means a great deal to them but wonât cause too much concern so long as Scotland and Northern Ireland do not become republics. The UK and British monarchy are two very different institutions.
A series is a summation performed on a list of numbers. Each term is added to the next, resulting in a sum of all terms. Sigma notation is used to represent the summation of a series. In this form, the capital Greek letter sigma $\left ( \Sigma \right )$ is used.
Now we are going to take a look at function notation and how it is used in Algebra. The typical notation for a function is f(x). This is read as f of x This does NOT mean f times x. This is a special notation used only for functions. However, f(x) is not the only variable used in function notation. You may see g(x), or h(x), or even b(a). You can use any letters, but they must be in the same format - a variable followed by another variable in parenthesis.
